DisplayPort and HDMI output not working

[ Edited ]

Hello

 

I have updated my drivers just yesterday (3/13). I then connected DP to HDMI adapter, the software recognized the external TV.  Yay !!

 

I changed to the option to Clone = Built-in Display + External monitor and tried different resolutions.  TV's resolution is 1920x1080 however this resolution was NOT available, hence I created this manually (overwrote the existing one - I could not see the existing but it asked anyway).

 

I then tried option Clone = External monitor + Built-in Display and tried many different resolutions.

 

I could not get picture to external TV. 

 

I have windows XP Pro 32 bit.

 

Please help.

 

Thanks

Re: DisplayPort and HDMI output not working

Just checking and curious, what is the native resolution of the external TV?

Re: DisplayPort and HDMI output not working

1960 x 1080.

 

Tried different refresh rates as well.

 

Is it possible that Amazon bought Displayport cannot handle this?

 

Should I try the certified compatible ones mentioned in this knowledgebase?

Re: DisplayPort and HDMI output not working

 

Samsung TV is 1920x1080.  I don't see a resolution 1920x1080 in the control panel.  However, I see External display named "Digital Display Samsung".

 

I tried all resolutions in control panel but TV does not receive the signal. I then added custom resolution 1920x080 for Digital Display Samsung but not sure how to choose this resolution for Samsung TV.  It just sits there.  I use Clone Displays.

 

The max resolution possible on my screen is 1440 x 900.

 

Lenovo, please help.  This is a new laptop, should I return it?

Re: DisplayPort and HDMI output not working

If you use Clone Display, then the Samsung TV will be given the 1440x900 resolution of your screen.

Hitting Win+P and setting it to Extend or Projector only should get the Samsung TV to function at it's native resolution.

Thanks to everybody who posted.  I bought the DP -> HDMI adapter listed in lenovo.com website.  Now it works fine including audio.
